Abstract
A display device and a method of adjusting backlight brightness of the display device are provided. The method includes converting original RGB signals of each pixel to corresponding RGBW signals; determining the color and original brightness value of each pixel based on the gray value ratio of the original RGB signals of each pixel; determining the backlight brightness value of each pixel based on the color of each pixel after the original RGB signals being converted; and performing weighted average calculation on the backlight brightness values of each pixel after the signals being converted, so as to obtain a whole backlight brightness adjustment value of all pixels.
